Answer: Python Puzzler #3324

The answer is A. The program prints:

[1, 6, 11]

This answer was checked by running the program for real.

Why?

range(1, 13, 5) counts from 1 in steps of 5 and stops before 13.

The code again

print(list(range(1, 13, 5)))

Try it: change one number in the program and predict the new output before you run it.
